Sum of place value in a row is 30.

So the letter which comes in place of '?' is 'I'. 

Her the given number series is 11, 17, 39, 85, ?

$$\begin{gathered} 11 \\ 11 + 32 - 3 = 17 \\ 17 + (52 - 3) = 39 \\ 39 + (72 - 3) = 85 \\ 85 + (92 - 3) = 163 \end{gathered}$$

Hence, the next number in the given sequence is 163.

Alliteration is the one-word substitute for Commencement of words with the same letter.

Alliteration is a figure of speech which is identified as the occurrence of the same letter or sound at the beginning of adjacent or closely connected words.

Justification:      

In the first and third statements, the common word is 'na' and the common word is 'are'.

So, 'na' means 'are'.
In the second and third statements, the common code word is 'tok' and the common word is 'bad'.
So, 'tok' means 'bad'.
Thus, in the third statements, 'tim' stands for 'they'.
